    I bought this sleeping bag about 6 years ago and it’s still my favorite. Perfect for me and my 50 lb doggo to snuggle in. Never cold. Yes, it’s a little bulky but WORTH IT.

  • Kelly McBride

    I’ve had one for a few years. It has held up well and I have yet to come close to being cold when using it under the stars. A few times it has been caught on sharp branches and large thorns without me knowing and even with a good amount of force being used before I noticed it was hung up no tears occurred.

  • Sean Dinegar

    I bought this bag about a year and a half ago when my son and I started boy scouts. Since it has been one of my only lines of defence from some verry cold and wet nights. It has stood up beautifully. Warm, soft and the extra width for some of us larger framed guys is the best. The only downside I can possibly find is that even with the stuff sack it is still a little large to pack. Otherwise I absolutely love it.

  • Françoise DIEVAL

    This sleeping bag seems so warm, sweet and comfortable ! And those nice colors ! I will buy one, for sure.

  • Christina Mancusi

    I own 2 of these. Bought them to camp in 30 degree weather and it was perfect. I love them so much I even use them at home as an extra blanket when it’s cold. ?

    Got this bag and immediately took it on a 4 day fall trip with overnight temps below freezing here in Wisconsin. I was over-prepared and managed to be sweating the first night with thermals on. The subsequent nights I was warm and cozy in this bag in just boxers. Seems like a very well constructed bag, the zipper didn’t snag at all or anything. Overall a fantastic value.

    Just used the Celsius XXL 0 Degree Sleeping Bag for two 34 degree nights in the Poconos mountains. Was very warm and the flannel lining feels luxurious on my skin. Love the bag. Highly recommend.

    After having a cold bad experience in the Mojave desert I bought two Celsius XXL 0 Degree sleeping bags. The bags are comfortable and warm. If I could give six stars I would.

    Am I the only person who has terrible memories of camping when younger? My sleeping bag always came unzipped and I was usually freezing, counting the hours until we could get up. I then spent the next two days in a coma because I was so tired. When I purchased the Celsius XXL Sleeping Bags for myself and my husband, those memories were gone! I can’t believe how warm and comfortable those sleeping bags are. We zip them together for a larger shared sleeping space. We really like having extra room because we are larger people. My kids are always trying to sneak into our sleeping bags because they are so soft. Never once have I been cold and I sometimes pull them out for movie nights at home. Really everything you’d want in a sleeping bag. It can make such a huge difference in how you sleep and enjoy camping.

    This is the go-to bag for my teenagers to grab when we load up the car for the next camping trip. They call it “The Bomb”. I can see what they mean…when it’s packed in the compression sack, it definitely looks menacing (haha). But it’s also “The Bomb” because it’s flat out a GREAT bag to take camping. It’s warm, comfortable inside, durable, and reliable. So TETON Sports, in more ways than one, this sleeping bag is…THE BOMB!

  • Rodney Bennett

    If there is anything about customer service I know that this company does it well. When I had a problem with my product Teton was able to be empathetic to my issues and get me a solution that was not only satisfying but also showed me how much the company cares about its customers.
    I had gotten a defective sleeping bag and contacted customer service about this issue. My problem, although I won’t get into it, was complicated and I didn’t even know if it was solvable. But sure enough, Alexandra got back to me and helped me figure everything out. Not only did she have an amazing understanding of my situation but they were also so fast about the entire exchange. When I sent an email she responded within a 24 hour cycle, it was fantastic and saved me a ton of stress over the whole experience. Not to mention the sleeping bags feel so good I sometimes even lay it down in the living room to take naps in. Thanks Alexandra and Brooke!

    Teton Sports offers the very best in camping equipment. I have a Celsius XXL bag that I use for BSA camping events. Excellent bag. I am 6′ 1″ tall and this is a very comfortable, spacious bag. Winter camping, this bag has kept me warm and comfortable. Warmer months it is a great bag to sleep on top of for additional comfort and the occasional cool night that happens. Recently, our Troop camped at Skymont Adventure Camp in Tennessee. The zipper on my bag came apart and I was not able to get it zip again. Since all of Teton Sports equipment has a Lifetime Warranty, I contacted Teton Sports by email and within minutes received a reply from Alexandra at customer service. She told me what I needed to advance my claim. Today, less than a week later, I received an email from Alexandra that a new replacement bag was being shipped to me. I have Teton Sports equipment for all my camping needs; backpack, cot and pad, and a tent. I have never been disappointed in the quality and price of the equipment. If you are not seriously looking at Teton Sports equipment with their Lifetime Warranty, you are wasting your time and money. Thanks Teton Sports for great camping adventures and awesome customer service by Alexandra.
